Hi, well i use fan shrouds for my toroid. the distance between hole/spaces
isnt seen by the frequency we run TC's at. I have a on top of the burner
pizza cooker toroid i made, it has a 2 by 3 inch square hole on one surface,
doesnt seem to bother anything at all! There are a number of people on the
list using chicken wire strung over plywood forms, most are big coils. cul
